FIRE-GRATE.

Specification of Letters Patent.

Patented Jan. 3, 1911.

Application led November 12, 1910. Serial No. 591,968.

'Fo all whom 'it may concern:

Be it known that I, EBENEZER HALL- BRowN, a subject of the King of theUnited Kingdom of Great Britain and Ireland, and residing at Kelvinside,Glasgow, Scotland, have invented a certain new and useful Improvement inFire-Grates, of which the following is a specification.

The invention has for its object to provide a simple construction ofremovable grate particularly applicable to gas producers of therising-grate type. When coal bituminous in any degree is used inproducers of this type, the grate members, if arranged loosely in thegrate casing', are apt during the descent of the same to becomedislodged owing to the clinkering of the fuel and the adherence of theclinker to the grate members. This drawback is avoided by the inventionwhich is illustrated in the accompanying` drawings in which Figure l isa plan of the grate and Figs. 2 and 3 are sections on the lines ama, andb-b, respectively, Fig. 1.

Referring to the drawings, the fire grate comprises a casing A having acentral cruci form aperture within which are fitted the three gratemembers proper B, C, and D. The central member B extends longitudinallyacross the casing A while the members C and D extend laterally thereof.Each of the members C and D is of a length not exceeding the width ofthe central member B. The mebers C and D and the parts ofthe casingwhich they fit are formed with counterpart grooves and tongues. Thesemembers C and D are slid laterally into position and withdrawn in asimilar manner when required. When in position, they are held there bythe central member B the sides of which abut their ends.

The central member B engages at one end a recess E in the grate casingA, or may be recessed to be engaged by a tongue on the casing, and atthe other end rests upon a projection or sill F on the casing A uponwhich projection it is secured bya bolt G or other suitable means. Thus,upon removal of the bolt G, the central member B may be raised at oneend, withdrawn from its recess E at the other end and removed, afterwhich the side members C and D may be slid laterally toward the centerof the grate casing and also removed.

A fire grate constructed as above described permits the several parts tobe readily removed for renewal or repair and to be properly secured inposition.

Having' now described my invention what I claim and desire to secure byLetters Patent of the United States is The combination with ua gratecasing having` a cruciform aperture, of grate members proper adapted tobe fitted in the said aperture, said members including a central memberremovably secured to the casing, and side members held in place by thesaid central member, said side members being slidable laterally, forremoval, on removal of the said central member, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EBENEZER HALL-BROVN.
